Answer:

Perímetro = 8.925 metros

Step-by-step explanation:

La formula del perímetro de un rectángulo es:

perímetro = 2(ancho + largo)

en este caso:

p = 2(a+b)

a = 3b/4

b = 2.55m

a = ancho del rectángulo

b = largo del rectángulo

entonces:

sustituyendo el valor de la segunda ecuación

p = 2((3b/4)+b)

p = 2((3b/4)+(4b/4))

p = 2(7b/4)

p = 14b/4

p = 7b/2

p = 7*2.55/2

p = 8.925m

Answer:

(x, y) = (4, -3)

Step-by-step explanation:

Relative to straight east with angles measured CCW, the vector is ...

5∠-36.9° = 5(cos(-36.9°), sin(-36.9°)) = 5(0.8, -0.6) = (4, -3)

1) A boat traveled 448 miles downstream and back. The trip downstream took 14 hours. The trip

Serhud [2]

Answer:B

I think we are in the same class lol

Step-by-step explanation:448 divided by 14= 32

448 divided by 16= 28

B=speed of boat in water

Y= Speed of current

B+y=32

B-y=28

32 + 28 =60

60 divided by 2 = 30

32 -30 =2

B=30

Y=2

Find the value of (+328.62) – (+98.6). A. 230.02 B. 427.22 C. –427.22 D. –230.02

Jet001 [13]

Answer:

Option A - $(+328.62)-(+98.6)=230.02$

Step-by-step explanation:

We have given the expression $(+328.62)-(+98.6)$

We have to find the value of the expression ?

Solution :

Step 1 - Write the expression

$=(+328.62)-(+98.6)$

Step 2 - Applying symbol rule i.e. multiplication of positive into negative is always negative, $(-)(+)=(-)$

$=328.62-98.6$

Step 3 - Solve

$=230.02$

Therefore, The value of the expression is $(+328.62)-(+98.6)=230.02$

So, Option A is correct.
